Medical Leave Email Template

TL;DR

A medical leave email should tell your manager you need time off for medical reasons, give a return target, and stop there. You don't need to disclose your diagnosis, condition, or treatment — in the US, HIPAA and ADA both protect medical privacy. For mental health leave, the same applies; you can take it without disclosing details. The auto-reply should be similarly sparse — 'on medical leave' is the right level of detail, not the symptom list.

When to use this template

Use a medical leave email for planned procedures (surgery, scheduled treatments), unexpected medical needs (illness requiring multiple days off), or extended treatment (cancer treatment, mental health recovery). For same-day sick calls, use the sick-leave-email template instead.

Tips for writing a better medical leave email

1You don't owe details. 'Medical leave' is enough; the specifics are private. Your manager doesn't need a diagnosis or treatment plan.
2For mental health leave, same rule. 'Medical leave' covers it. Don't feel obligated to specify burnout, anxiety, depression, or therapy — those are protected health information.
3Use 'approximately' for the return date. Medical timelines slip; the buffer protects you from awkward conversations if you extend.
4FMLA in the US gives 12 weeks of job-protected unpaid leave for serious health conditions. Your employer can't fire you for taking it, and they can't demand details beyond what a doctor certifies in writing.
5If your employer asks for more medical detail than feels appropriate, escalate to HR. There's a legal line between 'doctor's note for FMLA' and 'tell me what's wrong with you.'

Frequently asked questions

Do I have to tell my employer what medical condition I have?

No. In the US, the ADA and HIPAA protect you from having to disclose medical details to your employer. Your employer can ask for a doctor's note certifying that you need leave, and the doctor can specify estimated duration — but they cannot require you to share your diagnosis. The same applies in most other countries (e.g., UK GDPR, Canada PIPEDA).

How long can I take medical leave?

Depends on the country and circumstances. In the US, FMLA gives 12 weeks of unpaid job-protected leave for serious medical conditions; many companies offer paid medical leave on top of FMLA. The UK gives up to 28 weeks of statutory sick pay. Long-term disability insurance can extend further. Talk to HR about the layered options — short-term disability, FMLA, employer-paid leave, etc.

Can I take medical leave for mental health?

Yes. Mental health conditions are covered under the ADA, FMLA, and equivalent laws in most countries. You don't need to specify the condition — 'medical leave' covers it, and a healthcare provider (including a therapist or psychiatrist) can certify the need. Many companies are explicitly supportive of mental health leave; your HR team is the first call to understand what's available.
